Google Kubernetes Misconfig Lets Any Gmail Account Control Your Clusters

Google Kubernetes Misconfig Lets Any Gmail Account Control Your Clusters
Jan 24, 2024 Cloud Security / Kubernetes
Cybersecurity researchers have discovered a loophole impacting Google Kubernetes Engine (GKE) that could be potentially exploited by threat actors with a Google account to take control of a Kubernetes cluster. The critical shortcoming has been codenamed Sys:All by cloud security firm Orca. As many as 250,000 active GKE clusters in the wild are estimated to be susceptible to the attack vector. In a report shared with The Hacker News, security researcher Roi Nisimi said it "stems from a likely widespread misconception that the system:authenticated group in Google Kubernetes Engine includes only verified and deterministic identities, whereas in fact, it includes any Google authenticated account (even outside the organization)." The system:authenticated group is a special group that includes all authenticated entities, counting human users and service accounts. As a result, this could have serious consequences when administrators inadvertently bestow it with overly permis

29-Year-Old Ukrainian Cryptojacking Kingpin Arrested for Exploiting Cloud Services
Jan 13, 2024 Cryptojacking / Cloud Security
A 29-year-old Ukrainian national has been arrested in connection with running a "sophisticated cryptojacking scheme," netting them over $2 million (€1.8 million) in illicit profits. The person, described as the "mastermind" behind the operation, was apprehended in Mykolaiv, Ukraine, on January 9 by the National Police of Ukraine with support from Europol and an unnamed cloud service provider following "months of intensive collaboration." "A cloud provider approached Europol back in January 2023 with information regarding compromised cloud user accounts of theirs," Europol  said , adding it shared the intelligence with the Ukrainian authorities. The Cyber Police of Ukraine, in a separate announcement, said the suspect "infected the servers of a well-known American company with a miner virus" at least since 2021, using custom brute-force tools to infiltrate 1,500 accounts of the firm. "Using the compromised accounts, the hacker gained access to the management of the service," the a

New Python-based FBot Hacking Toolkit Aims at Cloud and SaaS Platforms

New Python-based FBot Hacking Toolkit Aims at Cloud and SaaS Platforms
Jan 11, 2024 Cloud Security / Cyber Attacks
A new Python-based hacking tool called  FBot  has been uncovered targeting web servers, cloud services, content management systems (CMS), and SaaS platforms such as Amazon Web Services (AWS), Microsoft 365, PayPal, Sendgrid, and Twilio. "Key features include credential harvesting for spamming attacks, AWS account hijacking tools, and functions to enable attacks against PayPal and various SaaS accounts," SentinelOne security researcher Alex Delamotte  said  in a report shared with The Hacker News. FBot is the latest addition to the list of cloud hacking tools like  AlienFox, GreenBot  (aka Maintance),  Legion , and  Predator , the latter four of which share code-level overlaps with AndroxGh0st. SentinelOne described FBot as "related but distinct from these families," owing to the fact that it does not reference any source code from AndroxGh0st, although it exhibits similarities with Legion, which first came to light last year. The end goal of the tool is to hijack cloud, SaaS, and

Why Public Links Expose Your SaaS Attack Surface

Why Public Links Expose Your SaaS Attack Surface
Jan 09, 2024 SaaS Security / Data Security
Collaboration is a powerful selling point for SaaS applications. Microsoft, Github, Miro, and others promote the collaborative nature of their software applications that allows users to do more. Links to files, repositories, and boards can be shared with anyone, anywhere. This encourages teamwork that helps create stronger campaigns and projects by encouraging collaboration among employees dispersed across regions and departments.  At the same time, the openness of data SaaS platforms can be problematic. A  2023 survey  by the Cloud Security Alliance and Adaptive Shield found that 58% of security incidents over the last two years involved data leakage. Clearly, sharing is good, but data sharing must be put in check. Most SaaS applications have mechanisms to control sharing. These tools are quite effective in ensuring that company resources aren't open for display on the public web. This article will look at three common data leakage scenarios and recommend best practices for safe sh

The Definitive Enterprise Browser Buyer's Guide

The Definitive Enterprise Browser Buyer's Guide
Jan 02, 2024 Browser Security / Threat Protection
Security stakeholders have come to realize that the prominent role the browser has in the modern corporate environment requires a re-evaluation of how it is managed and protected. While not long-ago web-borne risks were still addressed by a patchwork of endpoint, network, and cloud solutions, it is now clear that the partial protection these solutions provided is no longer sufficient. Therefore, more and more security teams are now turning to the emerging category of purpose-built enterprise browsers as the answer to the browser's security challenges. However, as this security solution category is still relatively new, there is not yet an established set of browser security best practices, nor common evaluation criteria.  LayerX, the User-First Enterprise Browser Extension, is addressing security teams' need with the downable  Enterprise Browser Buyer's Guide , which guides its readers through the essentials of choosing the best solution and provides them with an actionable

Google Cloud Resolves Privilege Escalation Flaw Impacting Kubernetes Service

Google Cloud Resolves Privilege Escalation Flaw Impacting Kubernetes Service
Dec 28, 2023 Cloud Security / Data Protection
Google Cloud has addressed a medium-severity security flaw in its platform that could be abused by an attacker who already has access to a Kubernetes cluster to escalate their privileges. "An attacker who has compromised the  Fluent Bit  logging container could combine that access with high privileges required by  Anthos Service Mesh  (on clusters that have enabled it) to escalate privileges in the cluster," the company  said  as part of an advisory released on December 14, 2023. Palo Alto Networks Unit 42, which discovered and reported the shortcoming, said adversaries could weaponize it to carry out "data theft, deploy malicious pods, and disrupt the cluster's operations." There is no evidence that the issue has been exploited in the wild. It has been addressed in the following versions of Google Kubernetes Engine (GKE) and Anthos Service Mesh (ASM) - 1.25.16-gke.1020000 1.26.10-gke.1235000 1.27.7-gke.1293000 1.28.4-gke.1083000 1.17.8-asm.8 1.18.

Alert: Threat Actors Can Leverage AWS STS to Infiltrate Cloud Accounts

Alert: Threat Actors Can Leverage AWS STS to Infiltrate Cloud Accounts
Dec 06, 2023 Access Management / Cloud Security
Threat actors can take advantage of Amazon Web Services Security Token Service (AWS STS) as a way to infiltrate cloud accounts and conduct follow-on attacks. The service enables threat actors to impersonate user identities and roles in cloud environments, Red Canary researchers Thomas Gardner and Cody Betsworth  said  in a Tuesday analysis. AWS STS is a  web service  that enables users to request temporary, limited-privilege credentials for users to access AWS resources without needing to create an AWS identity. These STS tokens can be valid  anywhere from 15 minutes to 36 hours . Threat actors can steal long-term IAM tokens through a variety of methods like malware infections, publicly exposed credentials, and phishing emails, subsequently using them to determine roles and privileges associated with those tokens via API calls. "Depending on the token's permission level, adversaries may also be able to use it to create additional IAM users with long-term AKIA tokens to e

New P2PInfect Botnet MIPS Variant Targeting Routers and IoT Devices

New P2PInfect Botnet MIPS Variant Targeting Routers and IoT Devices
Dec 04, 2023 Malware / Botnet
Cybersecurity researchers have discovered a new variant of an emerging botnet called  P2PInfect  that's capable of targeting routers and IoT devices. The latest version, per Cado Security Labs, is compiled for Microprocessor without Interlocked Pipelined Stages ( MIPS ) architecture, broadening its capabilities and reach. "It's highly likely that by targeting MIPS, the P2PInfect developers intend to infect routers and IoT devices with the malware," security researcher Matt Muir  said  in a report shared with The Hacker News. P2PInfect, a Rust-based malware, was  first   disclosed  back in July 2023, targeting unpatched Redis instances by exploiting a critical Lua sandbox escape vulnerability ( CVE-2022-0543 , CVSS score: 10.0) for initial access. A subsequent analysis from the cloud security firm in September  revealed  a surge in P2PInfect activity, coinciding with the release of iterative variants of the malware. The new artifacts, besides attempting to condu

Kubernetes Secrets of Fortune 500 Companies Exposed in Public Repositories
Nov 24, 2023 Cloud security / Data Protection
Cybersecurity researchers are warning of publicly exposed Kubernetes configuration secrets that could put organizations at risk of supply chain attacks. "These encoded Kubernetes configuration secrets were uploaded to public repositories," Aqua security researchers Yakir Kadkoda and Assaf Morag  said  in a new research published earlier this week. Some of those impacted include two top blockchain companies and various other fortune-500 companies, according to the cloud security firm, which leveraged the GitHub API to fetch all entries containing .dockerconfigjson and .dockercfg types that  store credentials  for accessing a container image registry. Of the 438 records that potentially held valid credentials for registries, 203 records – about 46% – contained valid credentials that provided access to the respective registries. Ninety-three of the passwords were manually set by individuals, as opposed to the 345 that were computer-generated. "In the majority of cases, these creden

Kinsing Hackers Exploit Apache ActiveMQ Vulnerability to Deploy Linux Rootkits
Nov 21, 2023 Linux / Rootkit
The  Kinsing  threat actors are actively exploiting a critical security flaw in vulnerable Apache ActiveMQ servers to infect Linux systems with cryptocurrency miners and rootkits. "Once Kinsing infects a system, it deploys a cryptocurrency mining script that exploits the host's resources to mine cryptocurrencies like Bitcoin, resulting in significant damage to the infrastructure and a negative impact on system performance," Trend Micro security researcher Peter Girnus  said . Kinsing  refers to a  Linux malware  with a history of targeting misconfigured containerized environments for cryptocurrency mining, often utilizing compromised server resources to generate illicit profits for the threat actors. The group is also known to quickly adapt its tactics to include newly disclosed flaws in web applications to breach target networks and deliver crypto miners. Earlier this month, Aqua  disclosed  the threat actor's attempts to exploit a Linux privilege escalation fla

Researchers Uncover Wiretapping of XMPP-Based Instant Messaging Service

Researchers Uncover Wiretapping of XMPP-Based Instant Messaging Service
Oct 28, 2023 Privacy / Data Security
New findings have shed light on what's said to be a lawful attempt to covertly intercept traffic originating from jabber[.]ru (aka xmpp[.]ru), an  XMPP -based instant messaging service, via servers hosted on Hetzner and Linode (a subsidiary of Akamai) in Germany. "The attacker has issued several new TLS certificates using Let's Encrypt service which were used to hijack encrypted  STARTTLS connections  on port 5222 using transparent [man-in-the-middle] proxy," a security researcher who goes by the alias ValdikSS  said  earlier this week. "The attack was discovered due to the expiration of one of the MiTM certificates, which haven't been reissued." Evidence gathered so far points to the traffic redirection being configured on the hosting provider network, ruling out other possibilities, such as a server breach or a spoofing attack. The wiretapping is estimated to have lasted for as long as six months, from April 18, 2023, although it's been confi
